I'm not sure where you can get it in a store. But I got mine online. I cant remember where but I'm sure you can find a lot of websites selling it. Just make sure it is food grade 35% not industrial. I've been using it and it seems to be working but just burns and fizzes like hell. I also got a dropper (from regular drugstore) to extract from the container to the q-tips drop by drop. makes it much easier to handle and no mess created. Goodluck!
as for the homozon for detox...i havent been focused enough to keep taking it regularly due to its rather unpleasing taste. but I decided that this oxygen therapy might actually clear hpv all together because my dad had one strain of hepatitis (cant remember which) before and after doing the oxygen therapy for 2 years (first with disgustingly h2o2 drops briefly then switching to homozon) he got tested again and he was clear from hepatitis. sounds impossible but true. it had to be that because he didnt do any other types of therapy. unless his body miraculously took it out himself. so why not give that ozone therapy a try if you can stand the taste. personally i'm going to try to get back into the regimen to see if it works all together. !
